I have a pump that appears to be
running but not pumping water. This type of condition could happen for a number of
reasons. Check to ensure the pump is connected the right way round.
Then ensure the pump has a flooded suction and that the water
supply valves are turned on.Back to top

My Standard
(positive) twin pump will not start. Check the simple things first, make sure the fuse is
sized correctly and functional, check the power is turned on and
the circuit breaker is set, then check the wiring, it is easy to
screw down on the insulation rather than the copper tails when
connecting the wires.

A minimum flow under gravity is required for these pumps to
operate, specifically:

If when opening the outlet to be pumped, the flow is less than
this it will not be sufficient to start the pump.Back to top

I have a Standard (Positive) twin
pump and it pulses when the shower is running. This will probably be due to a blockage. This can be a
scaled up shower head or as a result of the shower
hose collapsing, resulting in back-pressure which causes the pump
to switch off and then on again once the pressure has reduced. Try
running the shower with the head and then the hose removed if it's
that type of shower to see if the pump will run constantly. If the
pump still pulses then the filters on the shower should be
checked.Back to top

I have a Standard
(positive) twin pump and it keeps running on. If this pump has just been installed, close both
isolating valves on the outlet side of the pump (or the service
valves integral to the flexible hoses, if fitted) and see if the
pump stops. If it does, then this indicates there must be a tap or
outlet being pumped that is open to atmosphere. Check the system
and find where the pump is pumping the water to.

If the pump does not stop when closing the valves, check to see
if the reed switch on either end have become dislodged.
Alternatively unclip each reed switch, one at a time from the brass
outlet and see if this stops the pump, indicating the float is
stuck up inside and needs removal and cleaning or
replacement.Back to top

I need to pump the blended water
from a shower valve to a shower head. Which type of pump can I
use?
You can only use a positive single pump for this type of
application. If the gravity flow is below the volumes specified
below then you would need to use an air switch connected to the
pump (if possible).

The only other option is a Universal twin pump pumping into the
valve. You can not use a Universal single pump as the Universal
pumps need to build up pressure against a closed valve to shut
down.Back to top

We have a Universal
(negative) head twin pump and the flow rate is too great. Is
there any way to reduce the pressure or limit the flow? The pressure the pump delivers the water at is directly
proportional to the amount of water being used. Therefore if your
problem is that the pressure is too great at the shower head,
fitting a larger shower head would increase the water
flow and the pressure will be lower, but remember you will be using
the water faster so your stored hot water will not last as
long. The simplest way of reducing the performance is to
close the outlet isolating valves down no more than
30% on both hot and cold flows thus restricting the water
flow. Never restrict the water flow on the pump supply side.Back to top

My shower is fed through a mixer
tap with the cold water coming from the mains and the hot water
from a gravity-fed tank. I need a pump to boost the hot side of the
system. What options can you suggest? The best way forward here is to use a Monsoon Universal
single pump, of a size to suit the shower you have. Where
cold water is being supplied to the mixer valve and hot has to be
delivered to the same unit, the pump has to be able to provide and
maintain water pressure on the hot side so that when the valve is
opened the pump senses the pressure drop and starts. For a standard
medium pressure valve we would recommend the Monsoon Universal 2.0
bar single.Back to top

What's the difference between
Positive (standard) and Negative (universal)
pumps?﻿
Stuart Turner Universal pumps are designed to
function under both Positive and Negative head
conditions whereas our Standard pumps are only for
use where an open vented Positive head condition
exists.

Where a gravity flow of water is present then this is known as a
Positive head condition.

However, the actual gravity flow required to operate a given
pump varies, as follows:

If the gravity flow available to a given pump is less than
that specified above, then this is considered to be a
Negative head condition. This could be due to a
restrictive valve or when an outlet (tap or shower head) is above
or level with the cold water storage tank.

My Universal pump keeps turning
on and off on its own. How can I fix this? Check for any visible leaks in the system. Check
the tap washers and pipe joints etc. If there are no visible signs
of leaks in the system, you will have to shut both hot and cold
isolation valves on the outlet side of the pump. You will have
isolation valves on the flexible outlet hoses or local to the pump
on the system. If the pump continues to cycle when both valves are
shut, then the NRV's (non return valves) are leaking.Back to top

I need to get my pump
serviced can you suggest a local engineer? Search for an approved service engineer in your area
using the service engineer finder on our web site or call our
PumpAssist helpline.

Alternatively, if you are in a position to disconnect the pump
and return it to us then we can carry out a full service of the
pump in our facility, call our PumpAssist helpline for a
quotation.Back to top

My pump seems noisy, is there
anything I can do to reduce the noise? As per our instructions ensure the anti-vibration feet
are fitted. Ensure all pipe work to and from the pump is
independently supported and that flexible hoses have only minimal
bends. Ensure that the pump is located on a stable platform.Back to top

My pump has 'run-dry
protection' which has cut in, how do I restart it? To reset the dry run protection, switch off the
electricity supply for 10 seconds and then switch it on again. This
process will reset the control circuit, returning it to normal
operation once again. Now open and close the taps, purging the
system of air and allowing the pump to switch off normally.Back to top

My pump keeps "humming", what
is wrong? This is a sign of the pump being jammed or stuck,
stopping the free rotation when required or alternatively this
could be as a result of an electrical issue.

This could be as a result of infrequent use in a hard water area
for instance where the seals or other moving parts can become
stuck. You will probably need a qualified service engineer to sort
this problem, call our
PumpAssist helpline for further assistance.Back to top

My pump is leaking, how can I
solve the problem? Turn off the isolating valves on both the suction and
delivery side of the pump. Then contact PumpAssist to arrange a
service visit if the pump is within guarantee, or for further help
and advice.Back to top

Flomate Mains Boost Pump

Does the pump comply with water
authority standards? Yes, it is WRAS approved and fully compliant! However in
accordance with WRAS regulations a double check valve must be
fitted before any appliance to avoid any backward
contamination.Back to top

Does the pump need a minimum
flow rate before the pump will start? Yes. The pump activates when an unassisted flow of at
least 0.6 litre per minute exists.Back to top

How much extra pressure and
flow can I expect?

Flomate will deliver up to a maximum of 12 litres per minute (in
accordance with current UK water regulations) and will provide a
minimum of 1.5 bar on top of the existing incoming mains water
pressure.

Flomate Mains Boost Extra systems will boost incoming water
pressure to 3 bar and 16 litres/min for up to 40 minutes at a time
(depending on model selected - see product specifications for
guidance).

Flomate extra models are suitable for use with unvented
cylinders and can provide a compact and effective solution if the
mains water supply to the cylinder is inadequate.

Most manufactures of unvented cylinders recommend a minimum
water supply input of 1.5 bar and 20 litres per min to give an
adequate supply when more than one outlet is used. In such
circumstances and to meet these specific requirements, the Flomate
extra 200 & 300 units would be most suitable.

The smaller Flomate extra 60/80/100 units do not meet the
recommended minimum flow but if there is a poor mains supply, they
may provide a sufficiently improved performance where space is
limited.

Check that the flow of water available to the pump is at least
0.6 litre per minute.

Check that the supply cord has been secured via the exposed
conductor and not via the insulation.

Please refer to the installation manual supplied with the pump
for more information.Back to top

My pump starts intermittently
or continues to run when all pumped outlets are closed? This could be either a pump or system issue. To diagnose
where the problem lies shut down the outlet isolation valve.

If the pump stops then there is a problem with the system, this
could be a leaking tap or a leak in the pipe joints for
example.

If the pump continues to run or start intermittently then there
is a problem with the pump. Contact PumpAssist on 0844 98 000

Macerators and Lifting
Stations

Are there any building
regulations to consider before installing an additional bathroom or
utility room? Yes. Building regs allow a macerator to be installed
where there is already access to a WC, so if your property has a
toilet then you will be O.K. However you will need to comply with
Electrical regulations if running new appliance cable within a
kitchen or bathroom.Back to top

Can I put anything in the WC,
will anything block the unit? It is designed to work just like a WC, so it will remove
WC waste and water. But as is the case with a standard WC, items
such as sanitary towels and condoms could block or jam the
unit.Back to top

Can I fit an WC2 or WC3 macerator below the
toilet, under the floorboards perhaps? No. The units must be fitted directly behind the WC.
Please refer to the installation
guide.Back to top

Is it noisy? No, the wasteflo range operates at less than 60 dB, which
is no noisier than the noise produced when flushing a toilet. Their
low noise levels mean they can be located anywhere. Please refer to
the installation
guide for installation recommendations.Back to top

Will I need inlet adaptors to
connect pipe work to the unit? No, each unit comes with inlet adaptors included.Back to top

How far from the soil pipe can
they be located? The WC2
and WC3 macerators
can pump up to 52 horizontally and 5m vertically. The WC2 or LS5 lifting
station will pump 72m horizontally and 7m vertically. Remember you
must pump vertically and then horizontally. Please refer to the installationguide for
further details.Back to top

What is the pipe diameter
required to remove waste? The Wasteflo WC1, WC2 and WC3 macerators feature an
outlet adaptor which can easily be configured for use with either
22mm, 28mm or 32mm diameter waste pipe.

Note though that the use of 32mm diameter pipe wil maximise the
vertical and horizontal distances that these products can pump
waste.

The Wasteflo LS5 Lifting Station requires the use of 32mm
diameter waste pipe and this should not be reduced.

Can I connect a WC Pan to the
Lifting Station? No. This is purely a lifting station NOT a
Macerator.Back to top

Can I use the LS5 lifting
station with a washing machine or dishwasher? Yes. The LS5 is designed
to withstand maximum water temperatures of 70°C through the top
inlets. Washing machines and dishwashers MUST be connected to the
top inlets. Please refer to the installation
guide.Back to top

Can I use the LS5 lifting
station with a sink and waste disposal unit? Yes. It is recommended that no small solid food waste
such as fruit pips are introduced into the lifting station as these
will cause the unit to jam and may cause damage.Back to top

What can I use to clean or
disinfect the unit? The Stuart Turner Wasteflo range doesn't require
specialised disinfectants or harsh chemicals. Standard cleaning
materials such as bleach or household disinfectants can be
used.Back to top

Are they easy to clean and
maintain? Yes. These units DO NOT require any special cleaning
regime or regular maintenance.Back to top

The pump isn't working, what
should I check? In the unlikely event of a pump failure check the
following:

Outlet Pipe - Check pipe and outlet barb are not blocked with
debris or kinked. Reservoir - Check reservoir is not blocked with
debris.

Note: Fault conditions should be checked by a
competent person. If these checks do not resolve the problem please
contact PumpAssist for further assistance.Back to top

Do I need to clean or maintain
the pump and how? The pump reservoir can be easily removed for cleaning
purposes by undoing the screw located at the front of the pump,
depressing the front and allowing the reservoir to be moved
downwards (care should be taken as there may be water in the
reservoir). The pump does not need to be removed from its fixings
to clean the reservoir. The quick release outlet barb can be
removed very easily by twisting and pulling out.
The pump should be flushed through with anti-bacterial wash every
12 months to avoid sludge build up in the pump reservoir.Back to top

Can the pump be fixed to a
wall?
Yes, the pump is supplied with a fixing kit and can be wall or
floor mounted. It's important to ensure that it is level. A spirit
level is built in to the pump's casing to aid levelling the pump.
x2 screw holes can be found on the back plate of the pump for
fixing to a vertical surface.Back to top

Can the pump be located
outside?
No, do not position this pump externally it is designed for
installation indoors only.Back to top
